Ok, the pin basically spins with just my fingers, that's new bushing time then?!

Yes thats worn out.

I've got some new ones on the way, along with hardware. I'm amazed how quickly I went through them though, 20 hours doesn't seem a very long time. I've ridden some pretty rough stuff, but not for a long amount of time. Anyway, hopefully that sorts it

How loose is too loose? What's the risk in riding it anyway? I sanded mine down so I could remove it by hand, getting it out was a chore and I want to be able to swap springs in the parking lot until I get my spring rate figured out.

Mount the shock on a vice with the hardware installed. If there's noticeable side-to-side play, it's too loose. If the interface is firm but articulates freely, you're good to go.

If you can feel a knock then it's too loose. There's no real harm in riding it loose, it's just really annoying.

Back to square one. If anything, the knocking is worse now. I replaced the shock bushings and hardware, they were pretty worn out despite being barely ridden. I don't think it's a pivot bearing because I can't fell any sideways movement, and without the shock in they all feel smooth, however I've ordered some new ones just in case

On compression or rebound, whether with my hand on the top tube or sitting on the bike, there is a distinct knock which can be felt through the whole bike, even the handlebars. I've tried more and less preload on the spring, I've torqued the bolts up to spec. The damper feels fine cycling it in my hand, just smooth as it should be, and the rebound and compression adjusters all work as expected.

I don't think it's the check valve, you can hear that's a different noise when I put the lockout on

Have checked and it makes the same noise and knocking with or without the spring, and with or without the LOK on/off

Presumably this is the damper then...?

I would once again take the shock off the bike, remove the spring, and compress the damper by hand. If the knock takes place within the damper, it should be felt clearly that way.

If the shock was serviced just a while ago, have you contacted the shop in question? That would be the obvious way to go.

No knock at all when compressing with my hand, just feels smooth. Yep, have been chatting with them and they've already sent me new hardware to try, they'll figure it out!

I don't have access to another shock to test, but I may try bolting some wood with holes drilled at the right eye to eye and see if I can still feel any knock.

Update on this; turned out to be the main piston band causing the knock. The Mojo guys honoured some service work on it and it's arrived back in perfect working condition. Top blokes, very patient with all my questions, sorted quickly and easily

Nice to hear that there was a happy ending.
